Answer 1

I started having this error in my projects in XCode 4.2, and had a tough time figuring it out with the new project layout.

Make sure you go into the Project Settings and change the Code Signing Identity to a development profile for the Debug setting in the target settings. It's a bit easy to miss because the Project settings come up first, and there are identical looking Code Signing Identity settings there. But Target settings trump Project settings.

If that still doesn't work in XCode 4.2, go to "Edit Schemes" - in the project drop down, which is just to the right of the stop button, in the left segment of that custom pop-up. Select "Run" and make sure Build Configuration is set to "Debug".

In prior versions of XCode, it used to tell you whether you were in debug or release right up front; I haven't found where it's that obvious with the new "Schemes".
